BOTTLE-TAP.

SPECIFICATION forming part of Letters Patent N 0. 692,951, dated February 1-1 1902.

Application filed May 17, 1901.

To all whom it may concern:

Be it known that I, EDWIN WALKER, a cilizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Taps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

My invention relates to improvements in bottle-taps adapted to withdraw therefrom champagne and other effervescent liquids contained in bottles without removing the cork therefrom and by means of which the contents ofsuch bottles can be withdrawn at such intervals as may be desired without any considerable portion of the gases therein escap ing, so that the liquid remaining in the bottle will not deteriorate or spoil. This tap is of the type comprising ahollow screw adapted to be inserted into and through a bottle-cork and having valve mechanism therein by means of which the orifice in the screw can be opened, so as to allow the liquid in the bottle to flow out therethrough, and closing the orifice when desired, so asto prevent the further exit of the liquid and gases therefrom.

Heretofore the construction and operation of the screw-points of bottle-taps so as to adapt the screw to be readily inserted into the cork without the opening therein becoming more or less obstructed by particles of cork and the mechanism for opening and closing the orifice of the screw so as to effectually prevent the escape of the gases remaining in the bottle have been so difficult to accomplish that such taps have failed in practice to accomplished the desired result, especially after they have been in use a short time, as the valve mechanism is necessarily of such small size that it is difficult to make it so that it will operate effectually-for any length of time to close the orifice against the escape of gas. Again, the various types of screw-points used in the construction of bottle-taps were either so connected with the mechanism that it was difiicult, if not impossible, to clean the orifice out, or they have been so inserted in the ori- Serial No. 60,683. (No model.)

fice that when the tap passed through the cork they dropped out of the orifice, making it necessary to keep a stock of such points on hand to insert into the orifice each time the tap is inserted into a cork and without which the tap could not be used. These difficulties in the use of bottle-taps are so marked that they are of little use in practice. Ihave overcome these difficulties in bottle-taps by making the valve mechanism thereof of the screwcompression type with a resilient packing in the end of the screw, so that the screw and packing can be quickly removed therefrom, yet when operated to close the orifice in the screw effectually accomplishes the desired result, and the end of the corkscrew is extended below the end of the thread thereon, which extension is provided with lateral slots over which a spring-actuated sleeve having apoint thereon operates to effectually close the slots during the passage of the screw through the cork, and after it has passed therethrough the sleeve-point is moved downward by the action of the spring therein. These and other features of my invention are hereinafter set forth and described, and illustrated in the ac oompanying drawings, in which- Figure 1 is a side View in elevation of a bottle-tap embodying my invention. Fig. 2 is a Vertical section of the same.

In the drawings thus illustrating my invention, A is a screw having a head B and arms 0 0, extending laterally from said head. In the head 13 there is a Vertical valve-chamber D, from one side of which an orifice 0 ex tends through the arm 0, and from the bottom of the valve-chamber D an orifice a extends down through the screw A. In the bottom of the "alve-chamber D, around the upper end of the orifice a, there is a valve 01, and

in the valve-chamber, the upper portion of which is internally screw-threadedfl place a screwthreaded compression-valve E, provided with resilient packing e in the lower end thereof and a milled head E, by means whereof it can be operated.

The lower end of the screw A extends downward below the screw-thread thereon in the form of a tube F, which is a continuation of the orifice a. The tube F is provided with lateral slots f and has its lower end f closed, as is clearly shown in Fig. 2. Upon the tube F, I place a sleeve G, into which the tube F telescopes, the lower end of the sleeve G terminating in a sharp point g. In the sleeve G, below the closed end of the tube F, I place a spiral spring H, and through the slots f in the tube I and the upper part of the sleeve G, I place a transverse rivet h, which operates to retain the sleeve G in place on the tube F.

In operation when the point g of the sleeve G is inserted in a cork and pressure is applied to the arms of the screw to screwit into a cork the sleeve 9 moves upward on the tube F, so as to completely cover the slots f therein, and remains in this position until it has passed entirely through the cork, when the spring H moves it downward on the tube F to its normal position, as illustrated in the drawings, leaving the openingsfso that fluid will pass therethrough into the orifice a.

I have thus shown and described a convenient construction of a bottle-tap embodying my invention. I am aware, however, that the same may be considerably varied without departing from the spirit of my invention. Therefore,

What I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination in a bottle-tap of a hollow screw, valve mechanism for closing the orifice in said screw, and a spring-actuated telescopic section on the lower end of said screw, substantially as and for the purpose set forth.

2. The combination in a bottle-tap of a hollow screw, an enlarged head having a valvechamber therein,and a valve-seat around the upper end of the orifice in the screw, arms extending laterally from said head, one of which has an orifice therein communicating with the valve-chamber in the head, a screwactuated compression -valve in said valveohamber, operating on the valve-seat therein, a tubular extension on the lower end of the hollow screw, having. lateral openings therein, and a spring-actuated sleeve having a point on the lower end thereof adapted to telescope over the tubular extension and close the openings therein, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
